Abstract:
Objective To observe the changes of serum sphingosine-1-phosphate (S1P) level in acute attack of adult bronchial asthma (simplified as asthma) and explore its clinical significance in the pathogenesis of the disease.Methods Forty-five patients of outpatient and hospitalized admitted to the Department of Respiratory Medicine in First Affiliated Hospital of Jiamusi University from November 2015 to July 2016 were arranged to an asthma group;in thc samc period,25 healthy peoples in our hospital having passed physical examination were chosen and assigned in a healthy control group.Serum S1P levels were determined by enzyme-linked immunosorbent assay (ELISA) in the subjects,the differences of pulmonary function indexes,the percentage of 1 second forced expiratory volume (FEV1)in predicted FEV1 value,FEV1/forced vital capacity (FVC) ratio were compared between the two groups,and the correlations between FEV1％,FEV1/FVC and S1P level were analyzed by Pearson analysis.Results The level of S1P in serum of asthma group was significantly higher than that of the healthy control group (μmol/L:1.90 ± 0.32 vs.0.89 ± 0.17,P ＜ 0.01),the levels of FEV1％,FEV1/FVC were significantly lower in the asthma group than those in healthy control group [FEV1％:(68.26 ±22.83)％ vs.(97.46 ± 10.44)％,FEV1/FVC:0.69 ±0.13 vs.0.82 ±0.05,both P ＜ 0.01].In the asthma group,the levels of FEV1％,FEV1/FVC were negatively correlated to the serum S1P level (r =-0.801 and -0.648,both P ＜ 0.01).While the levels of FEV1％,FEV1/FVC were not correlated to the serum S1P level in the healthy control group (r =-0.048 and 0.183,P ＞ 0.05).Conclusion The serum S1P is increased significantly in patients with asthma,and it being an important inflammatory mediator may play a crucial role in the pathogenesis of asthma.
